What it is and where it sits
The ABB ACS580-01-073A-4 is a wall-mounted frequency converter in the ACS580-01 frame, built for 380... 480 V three-phase mains at 50/60 Hz — the class of drive an integrator drops into a cabinet to run a standard induction or permanent-magnet motor on a process line. At 25.7 cm wide x 20.3 cm deep x 63.6 cm tall and 20 Kg net (22 Kg shipping), it is a single-frame wall-mount unit sized for indoor panel-room mounting — one technician can shoulder it, two is the safer lift for overhead cable-tray work. The IP21 enclosure rating means the cabinet itself carries the dust and moisture protection; this drive is not specified for a washdown bay or an unfiltered machine-room door.
Signal headroom on the control side
Two analog inputs and two analog outputs are exposed at the control terminals, which is enough headroom for a process trim loop plus a follower reference without burning a fieldbus slot — useful where the line is running a PID on the drive itself rather than pushing setpoints over the network. Two analog inputs and two analog outputs are exposed; per-channel current limits, isolation class and update rate are not in the spec bundle, so size wiring and shield grounding to the terminal-block practice for the frame.
